Dual OP-AMP and 2.5V^±0.7%
Voltage Reference
Description
RoHS Compliant Product
SOP-8
The SPW8103S consists of 2 low-offset voltage amplifiers and
a high-accuracy 2.5V voltage reference in SOP-8 package.
The SPW8103S provides a low cost and space saving solution
for the application such as power supply and switching adapters.
The SPW8103S is available in a SOP-8 package. It can operate
over the ambient temperature range from -40 ^oC to 105 ^oC.
